我在运行应用程序时收到此错误。

错误:

这里指向了Recognize_Face.java:152):

(line 148) protected void onCreate(Bundle savedInstanceState) {
    (line 149) Log.i(TAG, "called onCreate");
    (line 150) 1super.onCreate(savedInstanceState);
    (line 151) getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    (line 152) setContentView(R.layout.activity_recognize__face);

谁能帮助我:/我真的很感谢您的时间,并为解决我的错误提供帮助。提前致谢!

您在布局XML中引用了一个自定义视图,并且该自定义视图没有publicContext,AttributeSet参数的必需构造函数。
